In her testimony during her February 2012 trial, Falconer, now 22, said her boyfriend, Glenn W. Jett Jr., threatened her to participate in his and Donald Anderson's plot in which Dion Smith was the victim.

Smith testified during Falconer's trial that Falconer, whom he met the day before, invited him to a house on Tausend where she was a guest. When he arrived, two men whom he identified as Jett and Anderson came from the back of the house armed with guns and beat him. After realizing they had mistaken Smith's identity, he testified, the trio told them they wanted money. Jett and Falconer took Smith's car to his house on Lexington.

Smith's wife, Asa Smith, testified that Jett and Falconer assaulted her and their then-18- and 17-year-old sons and ransacked the home.

Both Dion and Asa Smith testified that they considered Falconer to be a willing participant in the incident.

At issue was whether the prosecution presented enough evidence to establish, beyond a reasonable doubt, that Falconer was not acting under duress.

“There was sufficient evidence presented for the jury to determine that defendant was voluntarily participating,” the judges wrote. “Also, the jury could have inferred that (Falconer) was not under duress because she left twice and returned and continued to participate. Viewed in the light most favorable to the prosecution, and without second guessing the jury's judgment of witness credibility, we find” that the evidence was sufficient.

Prosecutors initially charged Falconer with 36 felonies, including conspiring to commit first-degree premeditated murder, a charge that carries a mandatory sentence of life in prison without the possibility of parole. The jury acquitted her of that charge and three others but convicted her of multiple other felonies that carry maximum penalties of life in prison — carjacking, torture, two counts of armed robbery, and separate counts of conspiring to commit that crime.

Falconer remains imprisoned at the Women's Huron Valley Correctional Facility in Ypsilanti. Her earliest release date is June 1, 2032. Jett, who is imprisoned at the St. Louis Correctional Facility, will not be eligible for parole until Oct. 21, 2043.

Anderson, 31, remains at large. Anyone with information on his whereabouts can call Crime Stoppers at 800-422-JAIL.
